Product Description

Overview

The three instruments in the testo 770 clamp meter family are ideally suited for current measurement in switching cabinets. One of the two pincer arms can be fully retracted into the instrument. This unique grab mechanism means that cables in tight switching cabinets can be easily grabbed. The automatic measurement parameter detection also ensures reliable work: in the current and voltage area, all three instruments detect direct and alternating current and select other parameters such as resistance, continuity, diode and capacitance automatically.
The testo 770-1 model is the standard version for daily measuring tasks, including starting current measurement.
The testo 770-2 also has a μA range as well as an integrated temperature adapter for all type K thermocouples.
In addition to that, the testo 770-3 includes real-time power measurements (Watts), Power Factor, and Bluetooth. The free Testo Smart App can be used for remote viewing, monitoring, data logging, and creating reports via Bluetooth. The powerful app allows you to create custom reports that include photos, data, and graphs that can be saved or sent via email.
